NOSE-GUARD FOR EYEGLASSES.

Specification of Letters Patent.

Patented. Dec. 10, 1907.

Application filed August 29. 1906. Serial No. 332.433.

tion of the same, reference being had to the accompanying drawings,forming a part of the speciicationhand to the reference-numerals markedthereon.

My present invention relates to improvethose ofthe t e emplo'in asubstantial rigid bridge 5aliid relativelf movable nolsd guards adaptedto engage the wearers nose to hold the eyeglasses positioned thereon,and the. object of the invention is to provide a deviceof this kindwherein the nose guards are guided to move substantially in line withone another, so that the relation 'of the noseengaging surfaces of theguards will not be altered while the guards occupy different positionsof adjustment, andfurthermore, to provide devices for enabling noseguards of the kind described, to be adjusted easily and conveniently.

To these and other ends the invention consists in certain improvementsandcombinations of parts all as will be hereinafter more fullyexplained, the novel features being pointed out in the claims at the endof the specification. Y

In the drawings Figure l is a front elevation of a pair of nose guardsconstructed' in accordance with my invention. F ig. 2 is a rear view ofa poigtion of the mounting.

`Figs. 3 and 4 are plan views of the mounting, showing the nose guard inopen and closed positions respectively, and Fig. 5 showsanother form oflmounting constructed in accordance with my invention.

Similar reference numerals in the several figures indicate similarparts.

In those types of eyeglasses employing a relatively yielding orresilient bridge Aadapted to be flexed to open and close the noseguards,

as well as those having the guards pivoted thereon, the relation of thenose-engaging surfaces of the guards is altered at each differentposition of adjustment thereof, and

while the inclination or angle of the guards may correspond with theslant of the sides of the nose when the guards are fit-ted thereon inone position, there will be .a variation in the angles of the nose guardand the sides of the nose in case the guards happen to be fitted thereonat a differentA point, and this adjustable feature is avoided by thepresent invention.

f. The mounting shown in Figs. 1--4y yinclusiveembodies the usuallensesl and@` havingpreferably rigid bridge 3 extendi 1g between `theirinner edges, the ends of this bridge extending inrear'of the plane ofthe lenses, and thence extending outwardly in alinement and in oppositedirections in a planein rear' of the lenses to form the guides 4 at eachend thereof. l

On the inner edge of each lens is fitted a suitableattachingldevice5.each`of these attachngdevices bein-g' rigidly secured to the bridge atpoints intermediate the central portio'n thereof and the guides, bythelugs' 6, and on the outer end of each of these guides of the bridge issecured a bearing lug v 7 having a .rearward extension 8 provided with abearing aperture, preferably angular in outline, to receive a slide 9having a corresponding outline, and the inner end of each slide is, inturn, provided with a corresponding bearing lug 10 having a forwardextension 11` provided with a bearing aperture to sli'dingly receive thecorresponding guide formed on thebridge, these guides being preferablyangular or rectangular in cross section and the apertures in thebearinglugs".v

close fit that will prevent relative rotation between these parts. y

The nose guards 12 are secured preferably in fixed relation on theircorresponding slides 9, the nose guards shown in the present beingcorrespondingly formed to' insure a instance being of an ordinary form,and hav- 1 l ing its attaching lug 1`3 suitably twisted to lie flatwiseagainst the rear surface ofthe slide where it is suitably secured, suchas by a' fastening screw 14, thenosc-engaging surfaces of the guardsbeing suitably-set 'or adjusted to correspond to the surfaces they areadapted to engage on the wearers/nose. It is preferable that theseguardsshould autov matically engage and obtain the requisitev hold against thewearers nose, and to accomplish this result, it is preferable to providea helical spring i5 on each of the guides on the bridge and having itsends resting against the bearing lugs 7 and 10 on 'the bridge and sliderespectively, the normaltendency of this spring to expand serving toylosv proximate the` nose guards and produce a clamping action on thenose when interposed between them, the lugs ,7 connecting the bridge andthe attaching devices serving as stops for limiting the inward movementof' the guards under the action of the springs.

In the present instance, thenose guards are operated by levers 16 havingfinger-engaging portions' at their forward ends adapted to be graspedand pressed together by the thumb and foreiinger of the wearer inapplying and removing the eyeglasses, each lever .having a screw 17 forpivotally connecting it` l to its corresponding attaching device on the.

lens, and at its rear-'end it has an aperture 18 preferably in the formof a radial slot,l and adapted to receive a projection 19 on the slidecarrying the nose guard, the forward ends of the levers preferablyextending forward of tlie plane of the lenses and being suitably formedto provide finger grips. 20.`

As the finger-grips on the guard operating I lenses are pressedtogether, their rear ends coperatinwwi-th theslides will move the latteroutwardly to produce a separation of the guards to en'able theeyeglassestobe fitted to, or remnved from"the'wearers nose, theoperating springs beingcompressed between the bearing lugs on thebridgaand slidesfrespec tively, and when the finger grips are released,

,these springs serve to automatically proxi- 'mate the nose guards,7 andbring them into proper engagement with-the-wearersnose. A

In the mountingl shown in Fg.5 the bridge has its ends formed -intoloops-or doubled portionsZl arranged preferably in rear of the plane ofthelenses, the inner and outer arms 22 and 2S-of each/loop beingprovided with a -bearing'aperture adapted'to serve vas guides for theslide 24 having the nose-'guard 25 secured at its inner end, this slidebeing'preferably rectangular orotherwise angularm cross sectionl and theguiding apertures being formed `to correspond in order to prevent relaly the latter being suitably formed to enable it to be operated by thewearers finger, and having its rear end bent downwardly and arranged tocoperate with an aperture 29 formed in' the slide 24, operation of thelever serving lto proximate and separate. the nose4 guards.

The nose guards in this form of the invention are also .automatic in.operation, that is to say, they are larranged to move into engagementwith the wearers nose when the operating levers are released, and thisis accomplished by a spring 30, one spring pret erably serving tooperateboth guards, the spring being soldered or otherwise secured tothe inner surface of the arched or interinedicurvature having shorterradii than the` arched or curved portion of the bridge which they restopposite to, and, as the guards are separated, these spring arms have airolling motionV on the bridge which serves to dis tribute the bendingaction on the spring and thus prevent breakage.

Eyeglasses constructed in accord ance with l,my invention do not requirefrequent adjustment of the nosegu'ards in order for them to properly fitthe wearers nose, as the relative movement of the guards issubstantially in alinement with one another and therefore the relationofthe nose-engaging portions of the guards will not be disturbed y thedifferent positions occupied by the guards, and by providing theoperating levers aving iinger grips for operating the guards, thedesired leverage may be obtained to iii- -sure an ease of movement ofthe guards. Moreover, the present invention enables the lenses to befirmly secured in fixed relation, and thereforev the opticalffrelationsthereof cannot be disturbed as in -those types of eyeglasses employing aresilient or spring bridge or other loose'or yielding connectionsbetween the lenses.

By arranging the guides on the bridge substantially in line with theoptical enters of the lenses, and attaching the slit es to the `noseguards at intermediate points thereof, the slides and bearings aresubjected to the least friction and strain, as there are no forcestending totilt the guards out of their proper line of movement, and thisenables the guards to be easily operatedby the iiuger grips and avoidsundue wear of the 4moving parts.' y
